If you like we could take on Tycho today. It might divert focus from your charity issues.

Is all 'all'. I mean, light is fastest in vacuum which is least dense medium in the universe. So if light speed is a constant, where? So I think all is not 'all' hence universe is not 'all'.

Brother Tycho has been duly taken on.

By 'all' I meant the accepted idea that the Universe (Uni = 1) contains everything otherwise it would not be a Universe. I am aware of the Multiverse theory too but even that does not admit of anything existing outside this cosmos.

I think the constant 'c' is supposed to be the fastest speed light can attain, which in a vacuum.

Hmmm.....what?

BTW we seem to have hijacked this thread, again. How rude!

There are some threads that seem to have been created specifically for us. And we own such threads without apologies.

For example, Wakanyugi says the speed of light is a constant. I used to think that was true till I learnt that some 'things' can move faster than light.

Wakanyugi, is there a cosmic speed limit?

Einstein says there is a cosmic speed limit (the speed of light).

But recent evidence is casting doubt on this. For instance the finding that the Universe is not only expanding, but the further out you go the faster the heavenly bodies are receding away from us. Clearly this means there must be bodies that are flying away at faster than the speed of light - in which case we shall never see them.

The speed of light is possibly only a constant in our local Universe. In the greater unknown, we do not really know.

Which brings me back to my pet theory ' the only constant is the observer (consciousness)'

Cosmic intelligence is the constant observer.

Wow!

You mean, you agree with me?

A better expression would be 'we have equivalent mind prints so far'.

I used to think that we humans are progressing over time but now I realize that things are more complicated than that. We are regressing in certain things and progressing in others. Examples;

- we used to have a much more effective law and justice system in our traditional societies than we currently have. Cases in the past were decided quickly by elders unlike now in Kenya where you're lost in the court system and a lot of people get away with theft and murder.
- corruption has become even worse with the introduction of money in currency. in the old days wealth was mostly in the form of cattle, goats, sheep, land etc. no one could rob the community without them noticing.
- we've become much more unhealthy in modern times. If you look at very old pictures of Kenya say 1900s, you'll notice that not even the older women with kids were obese. now people somehow assume that a middle aged man or woman will have a belly
- whole neighborhoods such as buru buru, umoja etc have degraded over time as all playing fields were stolen and uncontrolled construction turns these places into a giant slum with lots of insecurity
- we've lost the sense of community that existed in the past with the result that there's now lots of lonely people in our modern societies
- we've benefited and lost from modern medicine. the benefits are the cures for diseases we didn't have before, the losses are from the harm caused by modern medicine such as over-prescription of medicines and resultant side effects, surgeries that shouldn't have been done, medical errors by doctors etc
- apartments built in the past - say the 60s and 70s used to be much better spaced and had lots of green space. Now we are dealing with the concrete jungle.
- also you'd think that modern architecture would be an improvement on the past but you only need to visit old Europe to see that the beauty and charm of old architecture was lost somewhere.
